My wife used to be a Civil Servant.
When claiming expenses for travel she queried which category bus tickets should be put in and was told to put them in with train tickets but also that no-one in her department had ever claimed for bus tickets before (taxis being more usual).
She wouldn't catch the bus regardless but if there was one from the station to where she was going with a reasonable frequency or a short wait time she would.
I was a civil servant for a while, and on one occasion when I had to attend a meeting in London, there was a tube strike. I happily got the bus from Paddington, and walked a short way to get to the venue, which wasn't directly on any bus route. I arrived at the meeting five minutes or so later than I should have.
Over half of my colleagues were much later than me having queued for taxi's. Those that arrived on time had left home earlier than normal and either walked to the offices or spent time waiting for a taxi.
No one had opted for a bus, and when I explained how I had got there, the reaction was incredulity! Though I'm not sure how much of that was for me walking a few hundred metres or for using a bus = probably a bit of both!
Personally, I don't mind that cash fares are being withdrawn. i haen't paid cash for a bus journey for years, probably since the metting incident!
I understand the concerns about particular groups being inconvenienced, but as we move inexorably towards a society that is less reliant on cash, I can only see this sort of thing becoming more common.
